Undine is a unit class in Yggdra Union. This class is handy with spears, giving them an advantage over the swordsmen, but they are weak against axe users. This class' signature ability is their high affinity in water, which gives them the ability to swim in it safely and grants them a performance boost during clashes. Because they are female only, it is revealed that they may not have reproduction capabilities; instead they survive by reincarnation, through the power of the Transmigragem. The signature move of the Undines is Diamond Dust, a variation of Blizzard.
